The article says: "On July 6, 2020, the U.S. Supreme Court ruled unanimously in both Chiafalo v. Washington and Colorado Department of State v.

That seems like a "may" rather than a "must", and also talks about punishing them afterward rather than about voiding their vote.

It means that if states have laws regarding how their electors elect, those laws are the final word.
